The standards SAE J1752/3 and IEC 61967-2 define a method for measuring the electromagnetic radiation from an integrated circuit (IC). The IC itself is mounted on a test board that is clamped to a special window in the top of the TEM cell. The test board is not inside the cell but becomes a part of the cell wall.
The connected spectrum analyser or receiver measures the RF emissions emanating from the integrated circuit and impressed onto the septum of the cell. The IEC 62132-2 standard is prepared for doing immunity test on integrated circuits in a (G)TEM set-up.
Teseq now offers with the GTEM 250A SAE a GTEM cell with excellent VSWR for improved testing in range above 1 GHz. In relation to traditional TEM cells has the GTEM based solution no cut-off frequency and provides an application range above 1 GHz.
